Listeria vs The Dairy Industry

In February I had the opportunity to attend the “Artisan Dairy Producer Food Safety Initiative Workshop” to learn about the Food Safety Modernization Act (FSMA) along with other leaders in the dairy industry here in Wisconsin. It was put on by the Wisconsin Cheese Makers Association and was offered at no expense thanks to a generous grant from USDA-NIFA. Marianne Smukowski, from the Center for Dairy Research (CDR) and Matt Mathison from the Wisconsin Milk Marketing Board (WMMB) were the trainers for the workshop. The workshop was a brief overview of the expectations that the FDA has put before every business in the food industry, from the large to the small plants. This workshop was geared towards the dairy industry, focusing on the hazards that arise, and how to put a detailed plan together to prevent them. One of the hazards that was of special interest, especially due to the sheer amount of news coverage that it has gotten in the previous months, was the elimination and prevention of Listeriamonocytongenes in raw milk, cheeses, and Ready-to-Eat (RTEs) products.

So what can be done to prevent the contamination of Listeria? First and foremost a detailed safety plan that segregates raw milk and the tools and equipment used before pasteurization from the pasteurized milk is absolutely necessary. This can be assisted by using a color-coding system to keep brushes, squeegees, pails, etc. from being cross-contaminated with raw milk. Just recently Nelson-Jameson put out a new Color-Coded Catalog highlighting the numerous products that can be put in place to create a zoning system to prevent the cross-contamination that is so dangerous to product. You can check out that catalog here. Another important part of preventing Listeria is developing an environmental cleaning, sanitizing and monitoring program. Nelson-Jameson carries a variety of ATP monitoring systems to help with this. Check out this previously featured, easy-to-understand blog, that breaks down what ATP is and what luminometers can do to assist in ensuring cleaning efficacy. We also carry quick swabs that can specifically be used to test equipment for Listeria.

Unfortunately, recalls due to Listeria keep popping up. Nelson-Jameson is provides the tools and instruments to help prevent recalls. Not only does Nelson-Jameson provide you the luminometers, swabs, brushes, and other equipment needed, but we also do our best to help our customers search out educational opportunities that can be so powerful in helping understand and combat food safety threats.

For instance, our partners at Cherney College have a variety of classes that could be helpful in preventing Listeria along with any other microorganisms from entering product. Some of the classes from Cherney college include: “Environmental Monitoring & Sanitation Essentials,” “Introduction to Food Microbiology-The Basics,” “Advanced Food Microbiology” along with a few others. Check out their website for dates. Mention that you are a Nelson-Jameson customer at checkout and receive 10%. In addition, the CDR has some great short courses, including, “Wisconsin Cleaning and Sanitation Workshop,” “HACCP Workshop,”, and “Milk Pasteurization” that can assist with helping plants become safer. Together, and through educational opportunities like those mentioned here, the food and dairy industries can take on the challenges of the Food Safety Modernization Act, fight food safety threats like Listeria, and ensure a safe food supply for the nation.
